I am now at a stage that I have little problems getting the AP to fly the approach. The problems starts going missed. For discussion, I will refer to the ILS 04 at KLEX. FAF is BLAYD. Sequencing on GTN750 is the following: BLAYD, Runway 04, 2000, HYK (VOR). Missed approach is climb straight ahead to 2000', then right turn towards the VOR climbing to 3100', enter the hold.
Going missed using the TOGA button the AP switches from LOC (green) to GPS (magenta). Nose pitches up 5 degrees as set in configuration. However, it does not start right turn at 2000ft. Goes beyond the 2000'. Not sure how far beyond the 2000' it will go. Tower usually asks me to turn before getting much further out on runway heading. I have a few questions:
1. Should the AP start the right turn at 2000'?
2. Do I have to enter values into the altitude preselect window, and if so, which altitudes? (DA, 2000', 3100'???)
3. Does the AP get its altitude info from the altimeter or GPS altitude during the missed approach? I would think pressure altitude.
4. Should it start the right turn at 2000' or does it follow a pre-determined GPS course where the 2000 plays no role?
5. At about DA a window pops up on GTN750 asking for continuing with approach or to go missed. It is late during the approach and at a very busy time. Other than using the TOGA button, is there a way to initiate the missed approach from the GTN750 earlier during the approach phase ?
6. Is there a way of entering decision altitude in the altitude pre-select window (or somewhere else that is in view as a reminder) other than in 100's of feet? If that value is entered, will the AP level off at the DA or keep on flying the GS beyond the preset altitude?
7. Will AP level off by itself upon reaching 3100'? I believe it will enter the hold.
8. Once in the hold, how do you cancel the hold to go somewhere else?
Thanks.
